Wound Therapy Initiated Wound treatment plan determined in accordance to treatment Arrange for MRP/nurse practitioner orders as required to begin plan of care including goal (healable, maintenance or non-healable) agreeance to professional referral recommendations Identify any potential barriers to wound treatment plan Caution: USE DRY WOUND HEALING Utilize toolkit to determine wound cleansing, debridement and dressing selection 1. Keep eschar dry South West Region Wound Care Program 2. No occlusive dressings Wound Cleansing Table and Dressing Selection and Cleansing enablers 3. Do NOT debride CAWC Product Picker chart 4. Avoid tourniquet effect when securing dressings CAUTION: When Using Compression 5. If eschar becomes wet/boggy – URGENT referral to
advanced wound care specialist is recommended Compression is typically contraindicated in the presence of peripheral arterial disease. In some
circumstances light compression may be beneficial, but only if arterial supply is sufficient.
Sufficient arterial supply should be objectively evidenced by diagnostic tests. In such cases, compression should be ordered by an advanced wound care physician or nurse practitioner only.
